Verfahren zum faltenfreien Führen eines Folienbandes undMethod for wrinkle-free guiding of a film strip and
Die Erfindung betrifft ein Verfahren zum faltenfreien Führen eines Folienbandes mittels Walzensystemen, insbesondere einer
Aluminiumfolie für Elektrolytkondensatoren, sowie eine Vorrichtung zur Durchführung des Verfahrens.
5The invention relates to a method for wrinkle-free guiding of a foil strip by means of roller systems, in particular an aluminum foil for electrolytic capacitors, and a device for carrying out the method.
5
Bei der Führung von Folienbändern über Walzensysteme, wie sie z.B. bei der Bearbeitung von Aluminiumfolie für Elektrolytkondensatoren in Ätz- bzw. Formierbädern üblich ist, entstehen insbesondere bei weichgeglühten Aluminiumfolien häufig Falten. 10When guiding foil strips over roller systems, such as those used when processing aluminum foil for electrolytic capacitors is common in etching or forming baths, wrinkles often occur, especially in soft-annealed aluminum foils. 10
Die vorstehend aufgeführte Störung ist nicht mit herkömmlichen Mitteln auszuschalten.The above malfunction cannot be eliminated by conventional means.
Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung zur Durchführung des Verfahrens anzugeben, bei welchen eine faltenfreie Führung eines Folienbandes mittels Walzensystemen, insbesondere einer Aluminiumfolie für Elektrolytkondensatoren, gewährleistet ist.The object of the invention is to provide a method and a device for carrying out the method, in which a wrinkle-free Guidance of a foil strip by means of roller systems, in particular an aluminum foil for electrolytic capacitors, is guaranteed is.
Diese Aufgabe wird bei dem genannten Verfahren erfindungsgemäß dadurch gelöst, daß das Folienband über mit einer Reliefstruktur versehene Walzen geführt wird.According to the invention, this object is achieved in the above-mentioned method in that the film strip has a relief structure provided rollers is guided.

Die erfindungsgemäße Vorrichtung ist dadurch gekennzeichnet, daß D.
The device according to the invention is characterized in that
die Walzen mit einem Rautenmuster versehen sind.the rollers are provided with a diamond pattern.
Die Vorteile der Erfindung werden an Hand von Ausführungsbeispielen näher erläutert. In der dazugehörenden Zeichnung zeigen:The advantages of the invention are illustrated by means of exemplary embodiments explained in more detail. In the accompanying drawing show:
Fig. 1 die Ansicht einer mit einer Reliefstruktur versehenen Walze.1 shows the view of a structure provided with a relief structure Roller.
Fig. 2 die Ansicht einer Walze mit "erhabener" Struktur und Fig. 3 die Ansicht einer Walze mit eingefräster bzw. eingeschliffener Struktur.Fig. 2 is a view of a roller with "raised" structure and 3 shows the view of a roller with a milled or ground Structure.
In Fig. 1 ist eine Führungswalze 1 mit den Lagerzapfen 2, 3 dargestellt. Auf der Oberfläche der Walze 1 befindet sich ein Rautenmuster 4. Die Aluminiumfolie 5, die in Pfeilrichtung über die Walze 1 geführt wird und vor der Führung über die Walze 1 z.B. einen gewellten Rand 6 aufweist, ist nach dem Verlassen der Walze 1 völlig faltenfrei. Wie der Figur zu entnehmen ist, weist die Aluminiumfolie 5 nach Verlassen der Walze 1 ein leicht eingedrücktes Rautenmuster 7 auf, das allerdings nur im reflektierten Licht zu erkennen ist, und welches die Weiterverarbeitung nicht stört.In Fig. 1, a guide roller 1 with the bearing journals 2, 3 is shown. On the surface of the roller 1 is a diamond pattern 4. The aluminum foil 5, which is in the direction of the arrow over the Roller 1 is guided and has, for example, a corrugated edge 6 before being guided over roller 1, is after leaving the Roller 1 completely free of wrinkles. As can be seen from the figure, the aluminum foil 5 has a slightly indented appearance after it has left the roller 1 Diamond pattern 7, which, however, can only be seen in the reflected light, and which the further processing does not disturbs.
In Fig. 2 ist eine Führungswalze 1 mit "erhabenem" Rautenmuster dargestellt. Dieses "erhabene" Rautenmuster erhält man vorteilhafterweise dadurch, daß man die Walze 1 mit einem Netzschlauch überzieht, dessen einzelne Fäden 8 in der Fig. 2 dargestellt sind. Die Netzfäden 8 bestehen z.B. aus Polyäthylen oder Polypropylen und haben einen Fadendurchmesser von ca. 1,6 mm. Die Maschenweite des Rautenmusters beträgt ca. 16 mm Seitenlänge.In Fig. 2 is a guide roller 1 with a "raised" diamond pattern shown. This "raised" diamond pattern is advantageously obtained in that the roller 1 is covered with a mesh tube, the individual threads 8 of which are shown in FIG. The net threads 8 consist, for example, of polyethylene or polypropylene and have a thread diameter of approx. 1.6 mm. The mesh size of the diamond pattern is approx. 16 mm on the side.
In Fig. 3 ist eine andere Ausführungsform der Führungswalze 1 dargestellt. Die Oberfläche der Walze 1 weist Vertiefungen 9 auf, die in die Walze eingefräst bzw. eingeschliffen sind. Diese Vertiefungen sind ebenfalls in Form eines Rautenmusters auf die Walze 1 aufgebracht. Auch mit dieser Ausführungsform wird ein faltenfreier Lauf der Aluminiumfolie 5 gewährleistet.In Fig. 3, another embodiment of the guide roller 1 is shown. The surface of the roller 1 has depressions 9, which are milled or ground into the roller. These wells are also in the form of a diamond pattern on the Roller 1 applied. A wrinkle-free run of the aluminum foil 5 is also ensured with this embodiment.

Η·Η ·
Das erfindungsgemäße Verfahren gestattet insbesondere das faltenfreie FUhren von Aluminiumfolien auch wenn die Folien durch den Herstellungsprozeß bedingt bereits wellig angeliefert werden.The method according to the invention in particular allows wrinkle-free Guiding of aluminum foils even if the foils are already delivered wavy due to the manufacturing process.
